Reaktionsschritte
Solid 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.60 g) was added to a stirred suspension of (4-methoxyphenyl)acetic acid (0.50 g) and 1-hydroxybenzotriazine hydrate (0.40 g) in 10 mL tetrahydrofuran. The mixture was stirred for 30 min, then methylamine (2.0 M in THF, 6.0 mL) was added. Stirring was continued for 12 h and the volatile material was subsequently evaporated. The crude residue was dissolved in 50 mL of EtOAc and washed twice with 50 mL of 1 M hydrochloric acid, twice with 50 mL of saturated sodium bicarbonate, and twice with 50 mL of saturated sodium chloride. Evaporation of the ethyl acetate gives 0.45 g of 2-(4-methoxyphenyl)-N-methylacetamide.
